PURPOSE:To aim at improving the insertion of a vibration rubber insulator and at enhancing the insulating effect of vibration, by forming a come-off checking mushroom section in a truncated conical shape, and by forming a neck section between a load bearing section and the mushroom section in a truncated conical shape. CONSTITUTION:A come-off checking mushroom section 5a for preventing a attaching leg of a compressor 1 from coming off and for damping the attaching leg and a bushing nut 6, is formed in a truncated conical shape. Further a cylindrical neck section 5c between a load bearing section 5b of a compressor vibration rubber insulator 5 and the come-off preventing mushroom section 5a is formed in a truncated conical shape. The relationship among the outer diameter d1 of the upper surface of the come-off checking mushroom section 5a, the outer diameter d2 of the lower surface of the come-off checking section 5a, the outer diameter d3 of the upper part of the neck section 5c, the outer diameter d4 of the lower section of the neck section 5c and the inner diameter d5 of an attaching hole 2a in the attaching leg 2 of the compressor 1 is selected such that, d1<d5<d2 and d3<d4<d5<d2. |
